With startx under IBM AIX

Under IBM AIX, if the X Window server is started without a display manager by startx, the X Window server is specified in the script /usr/lpp/X11/defaults/xserverrc or in $HOME/.xserverrc. The lines

if [ $XTOEXEC ]; then
    exec /usr/lpp/X11/bin/X $EXTENSIONS "$@"
else
    TEMP=`/usr/lpp/X11/bin/X $EXTENSIONS "$@"`
fi

can be modified for XbigX support:

if [ -x /opt/XSOXbigX/bin/xbigx ]
then
    EXTENSIONS=":1 "$EXTENSIONS
    Xbigx="/opt/XSOXbigX/bin/xbigx serverCommand"
fi
if [ $XTOEXEC ]; then
    exec $Xbigx /usr/lpp/X11/bin/X $EXTENSIONS "$@"
else
    TEMP=`$Xbigx /usr/lpp/X11/bin/X $EXTENSIONS "$@"`
fi
